建立了ICP-AES直接测定TZM合金中钛和锆的分析方法。采用基体匹配法消除基体干扰,对实验条件进行了优化。实验结果表明:回收率为96.33%—110.00%,RSD(n=5)均小于2.0%。本法简便、快速、准确度高。
A direct ICP-AES method for the determination of titanium and zirconium in TZM alloys was established. Matrix matching method is used to eliminate matrix interference and the experimental conditions are optimized. The experimental results showed that the recoveries were 96.33% -110.00%, RSD (n = 5) were less than 2.0%. This method is simple, fast and accurate.
